every hour. At the end of this time, operation goes on for 5 hours with constant set temperature, and indoor fan
speed is set to “LOW”. After 7 hours since “SLEEP” function was selected, Indoor Unit automatically stops (OFF).
5.14.3 “SLEEP” in Heating mode. During the first 2 hours, set temperature is reduced by 1°C each hour. At the end
of this time, operation goes on for 5 hours with constant set temperature, and indoor fan speed is set to “LOW”,
however anticold air drafts prevention function (with fan operating at “Breeze” - that is reduced - speed) has the
priority. After 7 hours since “SLEEP” function was selected, Indoor Unit automatically stops (OFF).
5.14.4 “SLEEP” in Auto mode. After 1 hour of operation since “SLEEP” function was activated, if control electronics
had selected operation in Cooling mode, set temperature is increased by 1°C; if control electronics has selected
operation in Heating mode, after 1 hour of operation since “SLEEP” function was activated, set temperature is
reduced by 1°C; if control electronics has selected operation in Fan mode, set temperature will not be changed;
during the second hour of operation since “Sleep” function was activated, operation of system will not be modified
and set temperature will not be changed.
5.14.5 “Sleep” function has a fixed and not modifiable duration of 7 hours, at the end of which “Sleep” function will
be automatically deactivated. If you desire to deactivate “SLEEP” function in advance, it will be sufficient to press
“SLEEP” button on remote control while “SLEEP” function is active.
5.14.6 If “SLEEP” function and “TIMER OFF” operation overlap, the remaining time of “SLEEP” function will be
cancelled at the end of “TIMER OFF” operation (Indoor Unit’s stop), if “TIMER OFF” setting exceeds 7 hours; if on
the contrary, “TIMER OFF” setting is less than 7 hours, th remaining time of “SLEEP” function will be kept even after
the end of “TIMER OFF” operation, up to default duration of 7 hours, at the end of which Indoor Unit will stop (OFF).
5.15 “ECO” function for Energy Saving operation [Models different from HKEU X)
5.15.1
“ECO” function is available in the following operation modes: Cooling mode, Heating mode and Auto mode.
It can be activated by pressing the special button (“ECONOMIC RUNNING” for HTFU X & HRBU X Models;
“ECONOMIC” for HFIU X Models; “ECO” for HSFU Models) on IR remote control.
5.15.2 Concerning all Models of Indoor Units mentioned above, indoor fan speed is set to “LOW”. This allows
to reduce noise level from Indoor Unit and electricity consumption, but volume of treated air decreases and
consequently necessary time increases for reaching the required degree of comfort. Therefore, “ECO” function
must not be activated if thermal charge inside the room is already high.
5.16 Operation in “POWERFUL” mode [HFIU X Models)
5.16.1
“POWERFUL” mode is available in the following operation modes: Cooling mode and Heating
